LIQUID-DISPENSING NOZZLE. i

Application filed October 22, 1920. Serial No. 418,789;

of the liquid is greater than the vclosing presl sure on the valve.

My invention is particularly directed to an improvement inthe dispensingnozzle located at the free end orp the flexible hose which leads from agasoline pump, whereby the gasoline which is left in the flexible hosewill be retained therein so that each purchaser of gasoline will receiveexactly the amount of gasoline registered by the pump, the valve at thesame time serv-l ing to prevent leakage at the nozzle, and being soarranged that it cannot be tampered with at the exterior.

A practical embodiment of my invention is represented in theaccompanying drawing, in which,

Fig. l represents the liquid dispensing nozzle in top plan.

Fig. 2 represents the same in side eleva-- tion.

Fig. 3 represents a section talren in the plane of the line lll-lll ofFig. l.

rllhe flexible hose which leads to the gasoline pump, not shown herein,is denoted by l. lt may be provided with a nipple 2 by means of which itmay be secured to the branch 3 of the dispensing nozzle by means of asuitable union l.

The dispensing nozzle is provided. with a partition 5 upon one side otthe lateral supply port 16, which partition forms the bottom of a recess6. A suitable cap 7 serves to close the mouth of the recess 6. The noz-vzle is provided with a partition 8, upon the other side or' the lateralsupply port 16, which partition has a discharge port 9 therethrough.

At the discharge end of the nozzle, a strainer l() may be located, whichstrainer is held in position by a union 11, which engages the nozzle andalso the iiange of a nozzle extension l2.

T he head i3 oit' the discharge valve serves to open and close thedischarge port 9. The valve stem 14 extends through the partition 5,into the recess 6 where ay spring l5 engages the stem for normallyholding the discharge valve closed. It is intended that this springshall be suiiiciently powerful to hold the valve closed against theweight oi the liquid inthe line back of the valve except when thedelivery pressure is exerted on the liquid as for instance, by theoperation of the pump. greater than the pressure of the spring l5,therebyl automatically opening the valve. The moment the deliverypressure stops, the valve will automatically close, thus holding theliquid in the line back of the valve so that on the next operation ofthe pump, the discharge of the liquid from the nozzle`i i mediatelybegins.

By the provision of this automatic discharge valve in the dispensingnozzle, an accurate measured supply of the liquid is ensured for eachcustomer, thereby eliminating all discussion as to who is entitled tothe liquid in the line beyond the pump, as so frequently happens in thetype of liquid supply to which this invention is directed.

lt is evident that various changes may be made in the construction, formand arrangement of the several parts without departing 'from the spiritand scope of my invention; hence l do not intend to limit myself to theparticular embodiment herein shown and described, but,

lWhat l claim is l. it. liquid 'dispensing nozzle having a lateralsupply port, a partition forming a recess on one side of the supplyport, a par tition having a discharge port therethrough on the otherside of the supply port, a valve for the dischargel port having its stemextending into said recess, and a spring in said recess engaging saidstem to normally hold the valve closed.

rlhis delivery pressure will be 2. A liquid dispensing nozzle having aenga-ging said stem to normally hold the lateral supply port, apartition forming :L valve closed, and a. cap foi' closing the mouthrecess on one side of the supply port, :i parof said recess.
